Question

我已经在下面的代码

的帮助下在选项菜单上实现了通知计数代码

  @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);
        getMenuInflater().inflate(R.menu.main_activity_navigation, menu);

        MenuItem menuItem = menu.findItem(R.id.action_settings);
        menuItem.setIcon(buildCounterDrawable(4, android.R.color.transparent));


        return true;
    }

    private Drawable buildCounterDrawable(int count, int backgroundImageId) {
        LayoutInflater inflater = LayoutInflater.from(this);
        View view = inflater.inflate(R.layout.noitification_count, null);
        view.setBackgroundResource(backgroundImageId);

        if (count == 0) {
            View counterTextPanel = view.findViewById(R.id.badge_layout1);
            counterTextPanel.setVisibility(View.GONE);
        } else {
            TextView textView = (TextView) view.findViewById(R.id.badge_notification_1);
            textView.setText("" + count);
        }

        view.measure(
                View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),
                View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
        view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());

        view.setDrawingCacheEnabled(true);
        view.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH);
        Bitmap bitmap = Bitmap.createBitmap(view.getDrawingCache());
        view.setDrawingCacheEnabled(false);

        return new BitmapDrawable(getResources(), bitmap);
    }

这是我的xml文件（notification_count.xml）

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    style="@android:style/Widget.ActionButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:clickable="true"
    android:gravity="center"
    android:orientation="vertical">

    <RelativeLayout
        android:id="@+id/badge_layout1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

        <RelativeLayout
            android:id="@+id/relative_layout_item_count"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">

            <Button
                android:id="@+id/button1"
                android:layout_width="@dimen/_100sdp"
                android:layout_height="@dimen/_100sdp"
                android:background="@drawable/ic_dollar" />
        </RelativeLayout>

        <TextView
            android:id="@+id/badge_notification_1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignRight="@id/relative_layout_item_count"
            android:background="@drawable/circle_bg"
            android:gravity="center"
            android:text="12"
            android:textColor="#FFF"
            android:padding="@dimen/_10sdp"
            android:textSize="@dimen/_30sdp"
            android:textStyle="bold" />
    </RelativeLayout>
        </RelativeLayout>

这是我的circle_bg.xml

<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">

    <solid
        android:color="@color/green"/>

    <size
        android:width="20dp"
        android:height="20dp"/>
</shape>

但我没有在通知计数上得到完美的循环。我好像在下面

但我希望通知计数完全循环。所以请帮助我。

为徽章View

设置固定的宽度和高度

<TextView
        android:id="@+id/badge_notification_1"
        android:layout_width="20dp"
        android:layout_height="20dp"
        android:layout_alignRight="@id/relative_layout_item_count"
        android:background="@drawable/circle_bg"
        android:gravity="center"
        android:text="12"
        android:textColor="#FFF"
        android:padding="@dimen/_10sdp"
        android:textSize="@dimen/_30sdp"
        android:textStyle="bold" />

并从你的形状中移除，在这种情况下是不必要的

<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid
        android:color="@color/green"/>
</shape>

想通知计数的完美圈子
